GENERAL HISTOLOGY

Detailed explanation-1: -Some animals are known for their ability to regrow – or regenerate – body parts following dramatic injury. Starfish are among the most famous and dramatic examples, being able to grow an entire new body from just a single arm. Starfish also have the ability to regenerate neurons, something not seen in many animals.

Detailed explanation-2: -In autotomy, an arm is shed with part of the central disc attached, which continues to live independently as a “comet", eventually growing a new set of arms. Although almost all sea stars can regenerate their limbs, only a select few sea star species are able to reproduce in these ways.

Detailed explanation-3: -This is due to the starfish’s unique cells, which can de-differentiate themselves from skin or muscle cells back into stem cells.
